An off-duty Berkeley police officer was stabbed several times and three others were injured in a brawl involving dozens of people outside a Burlingame bar on Saturday night, a police sergeant said.

Two groups of people confronted each other outside of the Vinyl Room at 221 Park Road, off of Burlingame Avenue, shortly before midnight, Burlingame police Sgt. Don Shepley said.

A group of about 10 people had been denied entry to the bar because a private party was taking place inside, Shepley said. When members of the party exited the building, a fight broke out between the groups, he said.

Witnesses told police that somewhere between 40 and 60 people were involved in the altercation, Shepley said.

The Berkeley officer who was stabbed was taken to a hospital and is listed in stable condition. Shepley said there is no indication that the officer identified himself as such during the fight.

Also during the brawl, a bottle was thrown and struck a woman, causing a severe cut to the back of her head. Two others complained of pain after being punched and kicked, Shepley said.

The investigation showed no previous connection between the two groups, and no arrests have been made in the case, police said.

Anyone with information about the fight is encouraged to call police at (650) 777-4100.
